STEVAL-ISB038V1R：1 W Wearable wireless charger receiver based on STWLC04
The STEVAL-ISB038V1R is based on the STWLC04 integrated wireless power receiver, suitable
for wearable applications. The STWLC04 focuses on the 1 W protocol based on Qi; digital
control and precise analog control loops assure stable operation.
The STWLC04 can deliver the output power in two modes: as a power supply with configured
output voltage, as a simple CC/CV battery charger with configurable charging current,
charging voltage and termination current.
The STEVAL-ISB038V1R package includes the wireless charger receiver board; the PC GUI
application software for users to configure the most common parameters; the USB-to-I²C
converter board for connection between the PC and the wireless charger receiver
board.
